BENJAMIN F.A SAMBSoN, or lWESTA B'nooKFIELD, MASSACHUSETTS LettersPatent No. 104,500, dated June 21, 1870.

The Schedule referred t in these Letter-'s Patent n nd making part ofthe same To rall person-s to whom these presentsmay come:

Be it known that I, BENJAMIN F. SAMPsoN, of West Brookfield, of thecounty of' Worcester and State of' Massachusetts,-haveinvented a newanduseful Improvement in Hydfmulc llifIotors, or Turbine Water-Wheels; anddo hereby declare the same to be fully described in the followingspecification, and represented in the accompanying drawing, of lwhich-'.Figure 1 is horizontal section of' a water-wheel,

` `and its. directing-flume or conduit.

Figure 2 is a vertical section of' the two. y l

Figure 3 is a side elevation of the wheel.

The wheel-fiume'or directing scroll conduit A eu- Vcompasses the upper yset of lbrackets or floats of' the wheel B, and has apartitioma,extending through it` and terminating against the ,periphcryot' thewheel,Vv

in manner as represented, the same being'to divide the current owingnponopposite halves or'parts of the wheel into two separate currents,-whereby the water is caused to operate to better advantageon the wheel,as the outer current, ou its introduction to the wheel, will not bedisturbed or retarded by centrifugal force generated in the innercurrent by the wheel while in` rotation. l v

The wheel'B Iv construct with two series of curved one being `arranged.over the other, and separated from it by a flat ring, d.

The upper set of floats stands in dircctionsopposite to those of -thclower set, and both sets are disposed `between .two closeglleadafej, andaround a double tapering defiector," Oyextending betwcenthe two heads,such deflector, ywith the heads,.bcing formed as The shaft of the wheelis shown at D as working on a step, E, and within an arch or supporter,F, extended over the wheel, as represented.

Thelower series of buckets of' the wheel extendsl entirely below theflume or scroll conduit.

The purpose of'the deflector is to turn the water from the upper set ofbuckets by an easy curve into thespaces between the lower set, thusavoidingY the friction and disturbance of the water, and loss of powerincidentthereto, which would be likely to result were no such deflectoremployed.

In the operation of my hydraulic motor or turbine, Aas described, thewater will rst be delivered tothe vupper s'et of' buckets, against whichit will operate by impact or direct act-ion, after which it vwill dowagainst xfthededector, and by it be turned into the spaces bct'ween thelower series of bucket-s, and will ,flow outside therefrom, and operateby reaction to revolvethc wheel.

Thus it will he seen that the turbine is what is or may be termed adirect action, and a reaction waterwheel.

I claim as of my invention, the following, viz:

The wheel B, as constructed with the two series of curved floats b c,the flat ring d, the two'close heads c j, and the double taperingdeflector O, arranged as described; v
